1996 Ford F-150 Q&A
1996 Ford F-150 Question: Radiator Fluid
Replaced the radiator and reservoir after the hose blew off the radiator. The water consistency was a rusty orange mapley smell but it kept the engine cool, never overheat until the past week. If you run the engine and the air conditioning it would overheat. After putting the radiator and reservoir in, we put in the green coolant. The flow backed up into the reservoir and overflows out the top. The overflow is a foamy purplishly brown green. The a/c is blowing cool but the heater is not blowing. The gauge goes above the middle but not going to the HOT. - mrsmoore
It sounds like you have to really, really flush out your system, including your heater core. This may take multiple tries. It sounds like your heater core is plugged up with rusty coolant. Also, you should really replace the thermostat with the radiator work because if a hose blew off, I 'm sure the t-stat was over heated. and may be stuck which will cause the over flow problem. OK, if your trans fluid is mixing with your radiator fluid, it means that your trans cooler is leaking. There is a separate tank on your radiator to cool the trans fluid. I thought that you replaced radiator, didn't you? Does your trans have an additional cooler? If you trans fluid is mixing with your radiator fluid, then check your cooler lines into the trans and especially in the radiator. There has to be something that is allowing the trans fluid to mix with the the coolant, possibly the radiator is defective ( it can happen ) or the lines were did not match with the radiator and they poked a hole ( I have seen that too) Yes, I understand that the fluid is coming from the back, most likely from a on or near the trans. The key issue here is to stop the blending of the coolant and ATF which could only be happening in the radiator. Using a 'boneyard' radiator is very risky. Most likely the trans cooler tank is defective. First you need to confirm that the radiator is leaking internally. This can be done by pressure testing the radiator with the trans cooler lines off and everything else connected. It should not leak any coolant and hold at least 12 psi with out dropping for 15 minutes. If there is a leak, the coolant pressure will drop and even come out of the trans cooler line connection points on the radiator, especially the lower one. let me know how this test goes. So you tested the radiator as I suggested and it leaks? Ok, then I would definitely remove the trans pan and change the fluid and filter, but don't fill it all the way up, put in 4-5 quarts and then I would let the vehicle idle and then disconnect the return line to the radiator from the trans into a bucket (It will have the outflow) and let the fluid idle out until it is red and the water is out. It may take a few ( 6-8) quarts. This will get the coolant/fluid out of the torque converter etc. Then once that is done let the vehicle idle for a good while to let the rest of the water/coolant evaporate. Good Luck I am glad that the problem was discovered. - dandd
I know no fluid means money 4 new 1 I don't have and need truck 2 survive. Could 800lb load cause stinger 2 be lower than pan and leak out it
...eak was added to radiator 2 days ago. When fan is turned lots of vapors shoot out, smells like radiator fluid.
5.0 automatic 2 wheel drive 6100 mile also randomly spray a small amount of radiator fluid on the front right side , but never overheats.... and engine will studder and hesitate when...
